In physics, 1-dimensional systems are idealized physical models constrained to a single spatial dimension, where all relevant degrees of freedom vary along one coordinate while transverse dimensions are neglected or treated as frozen. Such systems are fundamental in statistical mechanics, condensed matter, and field theory, enabling exact or quasi-exact treatments of phenomena like phase transitions, transport, and quantum correlations. They exhibit distinctive behavior, including enhanced fluctuations, restricted ordering, and nontrivial topological or conformal structures, and are often described by specialized frameworks such as Luttinger liquid theory, integrable spin chains, or exactly solvable lattice and continuum models.
A Majorana fermion is a particle that would be identical to its antiparticle. Such an object has not yet been found. However, certain solid materials exhibit analogous behavior as if Majorana fermions were present through ...

When most people hear "polymer," they think of plastics. In our group, polymerization is a way to line up identical molecules like beads on a string and let quantum mechanics take over. Put magnetic building blocks in a one-dimensional ...
Scientists at TU Delft have designed a nanostring that, when poked, doesn't lose its energy to the environment immediately. Instead, the energy leaks out within the string, triggering a cascade of distinct vibrational modes. ...

We all know we live in three-dimensional space. But what does it mean when people talk about four dimensions? Is it just a bigger kind of space? Is it "space-time," the popular idea which emerged from Einstein's theory of ...

A team of US researchers has unveiled a device that can conduct electricity along its fractionally charged edges without losing energy to heat. Described in Nature Physics, the work, led by Xiaodong Xu at the University of ...
When water and ions move together through channels only a nanometer wide, they behave in unusual ways. In these tight spaces, water molecules line up in single file. This forces ions to shed some of the water molecules that ...

Physical systems become inherently more complicated and difficult to produce in a lab as the number of dimensions they exist in increases—even more so in quantum systems. While discrete time crystals (DTCs) had been previously ...
Researchers from the Institute of Metal Research (IMR) of the Chinese Academy of Sciences have stretched a chain of gold atoms by a record-breaking 46%, providing direct evidence of how fundamental metal bonds behave under ...
